The Genie 1256471GT Button Head Cap Screw, 1/4-20 x.625 is a genuine OEM fastener built for Genie S and Z series boom lifts and GTH telehandlers, including the S-80 J, Z-45 FE Hybrid, Z-45 DC, GTH-636, GTH-844, and GTH-1056. As a direct OEM replacement, this screw is manufactured to the same F835 grade and ZAG finish specifications as the original hardware, so it drops into place exactly as the factory intended. Cross-reference part number 1256471GT against your machine's parts manual to confirm it is the correct fastener for your application before ordering.
Key Features
- F835 Grade, ZAG Finish — Manufactured to F835 medium-carbon alloy steel grade with a zinc-and-gold (ZAG) corrosion-resistant coating, matching the original hardware specification for strength and durability in demanding jobsite conditions.
- Low-Profile Button Head Design — The rounded button head seats flush or near-flush against panels and brackets, making this the correct geometry for applications where a hex head cap screw would foul adjacent components.
- Exact OEM Dimensions — Thread size 1/4-20 and 0.625-inch grip length match the factory-specified values, ensuring proper clamp load and thread engagement without shimming or modification.
- Broad Genie Compatibility — Fits the S-80 J telescopic boom, Z-45 FE Hybrid and Z-45 DC articulating booms, and GTH-636, GTH-844, and GTH-1056 telehandlers — a single part number across multiple Genie equipment families.
- Structural Integrity — A correctly torqued, properly graded fastener keeps covers, guards, and structural brackets securely located. A fastener of the wrong grade or finish can loosen prematurely or corrode, compromising the assembly it secures.
A button head cap screw is a socket-drive fastener with a wide, low-profile domed head and a hex socket recess. The broad head distributes clamping load across a larger bearing surface than a standard socket head screw, making it well suited to sheet-metal panels, guards, and brackets where a raised head would create a clearance problem. When a fastener of this type is missing, under-torqued, or replaced with an incorrect grade, the joint it secures can work loose under vibration, leading to rattling covers, misaligned guards, or — in structural applications — progressive fastener fatigue. Using the correct OEM grade and finish ensures the joint performs as designed for the life of the machine.
